Under Wisconsin law, you only ever receive one deed to your property and you should have received it shortly after you closed on your property. If you take a look at your deed, you will notice that your name appears as a “grantee” but the bank is never mentioned. So, when you pay your mortgage in full, it is not necessary to update your deed.
What does need to be done is to have a “Satisfaction of Mortgage” document recorded with the Register of Deeds office. Financial institutions are required to record such a document within a specified timeframe. If you received a “Satisfaction of Mortgage” endorsed with a time, date and document number from a Register of Deeds office, nothing further needs to be done. If you have not received the endorsed satisfaction, you should check with your lender to be certain they processed the appropriate paperwork.
